Redetermination of 4-nitrostilbene

Abstract

In the title compound, C14H11NO2, the benzene rings are inclined to each other with a dihedral angle between their mean planes of 8.42 (6)°. The nitro group is almost coplanar with the attached benzene ring but is rotated about the C-N bond by 5.84 (12)°. This redetermination results in a crystal structure with significantly higher precision than the original determination [Hertel & Romer (1931). Z. Kristallogr. 76, 467-469], and the intermolecular interactions have been established. In the crystal structure, molecules are linked by C-HO hydrogen bonds to generate C(5), C(13) and edge-fused R33(28) rings

4-Bromo-4′-(dimethylamino)stilbene

“…The present work is part of a structural study of molecular complexes based on the matrix of stilbene which can be used as non-linear optical material (He et al, 2008). Our research group has developed the study of other related systems of stilbene (Moreno-Fuquen et al, 2008;Moreno-Fuquen et al, 2009). Though the present molecular system is centrosymmetric, information about its crystal structure is very important to the study of the general behavior of stilbenes because crystallographic information of stilbene systems is still rather small.…”
